[Webcast] Nuclear Power - from Last Gasp to Second Wind

This lecture reviews the tumultuous changes taking place in the nuclear industry; from its enthusiastic beginnings, through the darker days and on to the current resurgence. It explores the future of nuclear power as a major solution to energy security and climate change issues.


The History of Another Dimension - 50 Years of Bentley's V8 Engine

Dr Ulrich Eichhorn's lecture covers the original design and development of the Bentley V8 engine, from its introduction in 1959, in their S2 model, through to its present day form in the newly launched Bentley Brooklands coupe.

With contributions from several senior figures involved with the engine's creation and evolution over the last 50 years, the talk will describe how a well thought out concept and its careful execution have carried the design through to 2009, while other contemporaries have long since fallen by the wayside.

How to post a presentation?

Giving presentations at conferences or seminar series is a vital part of a researcher's professional life.  Listening to others' presentations is also one of the best ways to stay current with the frontier of a research field. While the audience in conference/seminar room is often limited, a presentation posted online can be virtually viewed by any interested audience. At iMechanica, users have started to post their presentation slides, quite often as the attachments of a post briefing the presentation.  Such a way is simple and effective, but may not be the best way for everyone for the following reasons:

Collapse of the Tacoma Narrows Bridge, 7 November 1940

In today's class of complex analysis, my co-instructor Scott Norris was lecturing on resonance.  He mentioned a YouTube video of the Tacoma Narrows Bridge.  Also instructive is the entry of the bridge on Wikipedia

Everything is miscellaneous (Video)

While preparing a talk on iMechanica , I came across the following video "Information R/evolution" by Michael Wesch, an assistant professor of anthropology at Kansas State University.  This thought provoking video echoes a recent comment on "The future of knowledge?"

Enjoy!

A fluid flow video

I just remembered another video that I had seen some time ago.  Many of you have probably seen it but here it is for those who have not. (The original page where I found it is http://www.maniacworld.com/Laminar-Reverse-Flow.html.)


Prof. Pat McMurtry's explanation is:

Eigenmodes of a square plate

The following video is a nice depiction of how the eigenmodes of a plate change with increasing forcing frequency.

An interesting coupling

A video that shows how some common couplings work. It's an advertisement but interesting nevertheless.  Does anyone know how the Thomson coupling works and what its main drawbacks are? It seems a bit complex and will probably have a higher rate of failure than simpler geometries - but maybe not?

Sony flexible OLED Display


Sony announces a OLED display on plastic film.

This is apparently the world's first full color OLED/organic TFT on a flexible substrate. Sony managed to create a flexible display with a size of 2.5 inch featuring a resolution of 120×RGB×160 pixel.
Other specifications of the flexible OLED display include 100 cd/m2
brightness, 1,000:1 contrast ratio and 0.3mm thickness of the panel.
Sony is demonstrating this new display achievement at the SID 2007 this week.  Please see the photoes: http://www.sony.co.jp/SonyInfo/News/Press/200705/07-053/index.html

IBM Airgap Microprocessors enabled by self assembly (Video)

An earlier post by Xiaohu Liu reported IBM's latest progress in microprocessors. IBM has figured out how to control and perfect the self assembly process to create trillions of tiny, nano-sized holes across a chip, which speed electrons that flow across wires inside the chip and reduce the power consumed by 15 percent.The following short video may help us understand a little bit more about the new technology. More videos, audio and images on this are available here (free, but registration needed)

Enjoy.

Self-assembled structures in a viscoelastic liquid

About a year ago, Zak Stone introduced me to YouTube with this video titled amazing liquid. I wonder how much of this behavior is understood. There must be a lot of fantastic videos of mechanical phenomena on YouTube. Perhaps we can embed them in iMechanica, and comment on them. Teng Li has provided an instruction of how to embed videos. You can check out a few other interesting videos in iMechanica video channel.

The comings and goings in a cell

Update 23 March 2007.  This wonderful educational video has now been removed from YouTube because it violates copyright.  What a pity!

Andre of Biocurious has just pointed out this terrific animation of the dynamics inside a cell. It brings many pages of textbook to life. Delightful. I've just followed Teng Li's instruction to embed the YouTube video below.
